Haplogroup C-M217 is the only variety of Haplogroup C-M130 to be found among Native Americans, among whom it reaches its highest frequency in Na-Dené populations. It would also make sense that this lineage may have originated in the Americas as that is the only Variety found amongst the aboriginal population.
Haplogroup C is believed to have arisen in East Asia [4] some 24,000 years before present. It is a descendant of the haplogroup M.Haplogroup C shares six mutations downstream of the MRCA of haplogroup M with haplogroup Z and five mutations downstream of the MRCA of haplogroup M with other members of haplogroup M8.
Two haplogroups are presented: Q-M242 and C-M130. [3] Haplogroup Q-M242, containing subgroups, is found in each tested population within the Americas. Haplogroup C-M130 is almost absent in Central and South America. [3] "Haplogroup C-M130 is dated to have expanded ~30,000 to 25,000 BP and haplogroup Q-M242 ~18,000 to 15,000 BP". [3]
Y-Chromosome Haplogroups all form "family trees" or "phylogenies", with both branches or sub-clades diverging from a common haplogroup ancestor, and also with all haplogroups themselves linked into one family tree which traces back ultimately to the most recent shared male line ancestor of all men alive today, called in popular science Y ...
A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1] [2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation.

Haplogroup CT is a human Y chromosome haplogroup.CT has two basal branches, CF and DE.DE is divided into a predominantly Asia-distributed haplogroup D-CTS3946 and a predominantly Africa-distributed haplogroup E-M96, while CF is divided into an East Asian, Native American, and Oceanian haplogroup C-M130 and haplogroup F-M89, which dominates most non-African populations.
